Lost Earnings Calculation: How Earning Capacity Is Evaluated After an Injury

An injury can affect much more than a person’s current paycheck. It may reduce work hours, limit the types of jobs a person can do, delay career growth, or prevent a return to the same occupation. In serious cases, the financial effect may continue for years.

Attorneys therefore look beyond wages already missed. They may also examine what the person could reasonably have earned if the injury had not occurred. This comparison uses employment records, medical restrictions, education, skills, and labor market information.

Lost Wages and Earning Capacity Are Not the Same

Lost wages usually refer to income that a person actually missed because of an injury. This may include time away from work, reduced hours, or lower pay during recovery.

Earning capacity is broader. It looks at a person’s ability to earn income over time. Someone may return to work and still have reduced earning capacity if the injury limits job choices, hours, advancement, or access to higher-paying work.

For example, a construction supervisor may return to a desk-based role after an orthopedic injury. The person is working, but restrictions may remove opportunities involving field work, overtime, or promotion. The question is what income the person could reasonably have earned without the injury.

Build a Reliable Pre-Injury Earnings Picture

A sound evaluation begins with the person’s work history before the injury. Actual earnings matter, but they don't always reflect full future potential.

Useful records may include:

• Tax and payroll records: W2 forms, 1099 forms, tax returns, pay stubs, and employer records can establish past compensation.
• Employment history: Job titles, duties, promotions, bonuses, overtime, and length of employment help show how the career was developing.
• Education and training: Degrees, licenses, certifications, apprenticeships, and job training can affect available occupations and wages.

A recent promotion, accepted job offer, or completed degree may matter if historical earnings have not yet reflected the person’s new work level.

Connect the Injury to the Work Loss

A lower income after an accident does not automatically prove that the injury caused the difference. The evaluation should identify how the medical condition affects the person's ability to work.

Medical records may describe limits involving lifting, standing, walking, sitting, concentration, stamina, or hand use. Functional testing may provide more information about the tasks a person can perform.

The key question is whether those limits reduce access to work. A restriction matters financially when it prevents or limits jobs the person would otherwise be qualified to perform. This connection between medical evidence and employment impact is central to calculating loss of earning capacity.

Evaluate the Vocational Profile

A vocational evaluation looks at the individual as a worker. The expert may review:

• Past occupations and job duties
• Education and training
• Transferable skills
• Physical and cognitive restrictions
• Licenses or certifications
• Current work ability
• Local labor market conditions

The goal is to identify realistic employment options before and after the injury and determine whether access to certain occupations or wage levels has changed.

Compare Pre-Injury and Post-Injury Capacity

One useful approach is to develop two vocational profiles.

The first asks what the person could earn before the injury, including realistic advancement opportunities. The second asks what the person can reasonably earn after the injury, considering current restrictions, skills, and available occupations.

The difference between those two earning paths may support a claim for loss of future earnings.

Both estimates should be based on evidence. The analysis should not simply choose the highest possible wage before the injury and the lowest possible wage afterward.

Consider Career Growth, Not Just Past Pay

Past earnings are often the easiest numbers to document, but careers don't always stay flat.

A younger worker may be completing training. An employee may have just been promoted. A professional may have a record of advancing into positions with greater responsibility.

Career growth should not be assumed without support. However, promotions, education, certifications, employer records, and established occupational wage patterns may provide useful evidence. Use the same care when deciding whether the injured person can retrain, move into another occupation, or work with accommodations.

Use Labor Market Evidence

A job may be theoretically possible but difficult to find in the relevant labor market. Vocational experts may research whether suitable jobs exist, what employers require, and what those jobs generally pay.

Labor market research can examine:

• Typical wages for suitable occupations
• Education and experience requirements
• Physical demands
• Availability of jobs in the area
• Full-time or part-time opportunities

This is useful when the injury prevents a return to the former occupation.

Include Other Compensation When Supported

Compensation may include more than base salary. Bonuses, commissions, retirement contributions, or other benefits may matter when reliable records show they were part of the person’s compensation. Attorneys and economic experts may need to determine how these items fit into the final damages analysis.

Work Life Expectancy Matters

Future earnings are not projected forever. The analysis should consider how long the person would reasonably have remained in the workforce based on factors such as age, education, occupation, work history, health, and accepted statistical data.

This is another reason projections should be individualized. People earning the same amount today may still have different career paths and expected years of employment.

Keep Vocational and Economic Roles Clear

A vocational expert may identify realistic occupations, pre-injury and post-injury earning capacity, and how medical restrictions affect employability. An economist may then use supported earnings figures to address wage growth, inflation, work life assumptions, or present value when needed.

Keeping these roles clear makes the final analysis easier to understand.

A Practical Example

Consider a 38-year-old electrician who suffers a serious hand injury. Before the injury, the worker had ten years of experience, held required licenses, worked overtime, and had begun supervising larger projects.

After treatment, permanent limits to grip and dexterity make full field work unrealistic. A vocational evaluation may identify the worker’s likely pre-injury career path and then examine transferable skills for jobs such as estimating, scheduling, or sales.

If those realistic post-injury jobs offer lower long-term earnings, the difference may support a loss of future earnings analysis.

Common Mistakes That Can Weaken the Evaluation

Several problems can reduce the reliability of an earnings loss opinion:

• Using one year of wages without context: One year may be unusually high or low. A longer earnings history often gives a more balanced picture.
• Ignoring career evidence: A promotion, new license, or completed training may affect future potential when it is properly documented.
• Assuming total disability: Some injured people can still work in another role. The analysis should consider realistic alternatives.
• Skipping labor market research: A suggested job has limited value if it doesn't match the person’s skills, restrictions, or the actual job market.

Objective analysis should account for both limitations and remaining work ability.

What Strong Documentation Should Include

Attorneys should gather employment files, tax records, resumes, education records, licenses, job descriptions, medical records, disability findings, and functional evaluations when relevant.

If bonuses, overtime, commissions, or expected promotions matter, supporting documents are especially useful.

Clear records make calculating loss of earning capacity more reliable because the expert can base opinions on the person’s actual history rather than assumptions.

Conclusion

Evaluating earning capacity after an injury requires more than comparing two paychecks. A reliable analysis considers past earnings, career direction, education, transferable skills, medical restrictions, realistic job options, labor market wages, benefits, and expected years of work.
